ING-GATE LAMP.

Application filed June 5, 1915.

T 0 all whom it may concern? Be it known that I, ALLAN Kinnwoon MAcnoNALn, a subject of the King of Great Britain, residing at Hamilton, in the county of VVentworth and Province of Ontario, Canada, have invented a new and useful Railroad-Crossing-Gate Lamp, of which the following is a specification.

It! i; invention relates to improvements in railroad crossing gate lamps, and consists of a two-way shield or ordinary railroad lamp; my improvement are, first, by which a common red, railroad lamp can be used to advantage for a gate lamp, second, to provide means that will permit the red light to be seen only by pedestrians, or vehicular trafiic which may be approaching the railroad crossing, and at the same time rendering the light invisible to engineers or trainmen approaching the highway crossing on the railway, thereby not confusing them, third, to afford means for increasing the power or brilliancy of the red light, that it may be more eflicient in warning the general public, of the impending danger.

I attain these objects by the device illustrated in the accompanying drawing, in which,

Figure 1 shown attached to the lamp; Fig. 2 a" front elevation of the same; Fig. 3 a top view of the device in disconnection with the lamp.

Similar characters of reference refer, to

and the objects of to provide means or danger signal is a side elevation of the device,

The device consists of two similar semicircular sections or parts A and B, forming a casing, having light outlets 3, and provided with light concentrators or reflectors A.

Specification of Letters Patent.

blind, adjustable to an similar parts throughout the several views,

Patented Nov. 1 8, 1915.

Serial No. 32,469.

The said parts are hinged together at O, and are fastened at 2 by a lock pin D, thereby forming a cylinder with open ends for facilitating the adjustment of the device to the lamp 6.

The device is suspended to the top casing 5 of the lamp 6 by means of the lugs E, which extend over the said top. The lugs E are also adapted to engage with the lamp handle 7, thereby preventing any chance turning, or misplacing of the device.

It can be readily observed that the device can be attached to any common railroa lamp without any special adjustment. Also it may be seen that by the use of the device the light is made more intense by means of the polished inside acting as a reflector, an by the concentrators l.

The open ended, cylindrical blind is applicable to lamps of the class described, either in halves as set forth, or may beset on over the lamp in one piece.

I claim:

1. In a railway crossing gate lamp having a two way cylindrical casing constituting a blind having both ends open, and two opposite openings in the sides thereof, light reflectors around said openings, and lugs on the upper part of the casing to suspend the casing from the dome of the lamp.

2. In a railroad crossing gate lamphaving a two way cylindrical casing constituting a blind having both ends open, and two opposite openings in the sides thereof, and light reflectors around said openings.
